CHIMNEY-CAP.

SPECIFICATION forming part of Letters Patent No. 394,337, dated December 11, 1888.

Application filed August 20, 1888. Serial No. 283,227. (No model.)

To (LZZ whom it may concern.-

Be it known that l, ADAM E. CLUTE, a resident of West Troy, in the county of Albany and State of New York, have invented certain new and useful Improvements in Chimney- Caps; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawil'lgs, and to the letters of refer ence marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

My invention relates to improvements in chimneycaps; and it consists of the novel construction and combination of parts hereinafter descriljied, and pointed out in the claims.

Figure 1 of the drawings is a side elevation of a chimney top and cap in position thereon. Fig. 2 is a top plan view of same. Fig. 3 is a central vertical sectionof the chimney and cap, taken on broken line :1: .r in Fig. 2. Fig. 4 is an inside plan view of one of the cornerpieces detached. Fig. 5 is a plan view of a sheet-metal blank adapted to be bent on two sides to form one side of the chimney-cap. Fig. 6 is a plan. view of one side of the cap detached and formed from the blank shown in Fig. 5. Fig. 7 is plan view of four sides of a cap in different sizes detached and packed one within another in the manner of packing for shipment.

The chimney-cap A is preferably made of four separate sheet-metal side sections, A A A A*, which are riveted together at their beveled ends to form a rectangular cap or cover, having inclined side walls, the cap being supported and anchored to a chimney-top by four corner-clamps, B, one at each chimneycorner and in the angles of the cap. The side sections may be made of cast metal or other desired material; but I prefer to cut them from sheet metal and in substantially the form shown in Fig. 5. The upper edge, a, of

each blank is bent over along the broken line a, Fig. 5, to produce a downwardly-proj ecting flange. These flanges form the sides of the mouth of the chimney-flue, as shown in Fig.

3. The edge u. on one of the beveled or diagonally-cut ends of the blanks is bent over along the broken line y to produce an overlapping fiange adapted to overlap the contiguous end of an adjoining side, as shown in Fig. (i represents the appearance of the blank as seen in Fig. 5 after the edges a and a have been bent over to form the required flanges.

The side pieces can be made of any desired length to fit different-sized chimneys.

As shown in Fi 1, 2, and 3, the two longer sides of the chimney are two and one-half bricks long, while the other two sides or ends are one and one-half brick long. The side pieces A are therefore designed for chimneysides one and one -half brick long, A for sides two bricks long, A for sides two and one-half bricks long, and A for sides three bricks long.

The side pieces are all made alike except in length, those of the same length being interchangeable.

The sides can be easily and closely packed together in a detached condition for shipment, as shown in Fig. 7, and need not be riveted or clamped together until they reach the chimney. The corner-clamps B are all made alike and serve to anchor the cap upon the chi1nney-top.

The clamp consists of two right-angular vertical sides, B and H, which are inclined at their upper ends at B and 13 to form a sup port for the inclined corners of the cap. The vertical sides are connected by and supporta fluke, B adapted to be anchored on top of the corner-brick in an intermediate course of bricks forming the chimney-top D. The inclined part is provided with a slot, B, adapted to receive a bolt, 1), which is passed down through the perforated angle-plate (l and through bolt-hole a in the side section, as shown partly by dotted lines in Fig.

The cap can be easily secured to an old chimney already erected, or to achimney during the process of erecting the chimney, as follows: to a new chimney by placing a corner-clam p, B, upon each corner of the chimney, so that the fluke l3 rests 011 top of the corner-brick immediately after the course gle-plates (Z upon the cap-corners with their central perforations in line with the bolt-holes a; then inserting the screw bolts 1) and screwing up the nuts Z) on the inside until the cap-sections are tightly clamped together between the plate (Z and the clamps l3. \Vhen the parts are so clamped together, the capsections are not only held tightly together and in place, but the cornerclamps are held tightly clamped against the corner of the chimney by the cap, so that it is impossible for the flukes B to work out from between the corners of bricks. The chimney-top is then completed by filling in the broken courses (1 and C To attach the cap to an old chimney-top, it is only necessary to clear away from between the courses of brick at the corners of the chimney and two courses down from the top suiiicient mortar to admit of the insertion of 0 the thin fluke B set up the corner-clamps,

attach the cap, and top out with the broken courses 0 and C as before described.

I am thus able to easily and cheaply pro it strikes the beveled or inclined sides of the cap surrounding the mouth of the chimney line and is thrown upward instead of downward, thereby increasing the upward current within the mouth of the chimney-flue.

The slot l3 in the inclined ends of the corher-clamps insures an easy fit of the cap upon the clamps after they have been anchored upon the chimney-corners.

Should chimn ey-tops of the same number of bricks in width and length vary slightly in size on account of variation in. amount of mortar used, the bolt-holes a and a will readily accommodate themselves to some part of the slots B, so that the clamping-bolts Z) may be easily inserted and secured in place.

The cap can be secured to the chimney-top in an y known inann er without an y corn cr-cl amps, as by n ails driven through the bolt-holes a, or by cementing the same to the chimney-top.

The flanged plates form a complete article of mamifacture which may be put upon the market in a detached condition and set up, as above described, when. and as desired.

'hat I claim as new, and desire to secure by Letters Patent, is

1. A chimney-cap formed of metal plates having on their upper edges an introverted flue-flange and on their ends diagonal lapping edges, which edges are fastened together, as by rivets, substantially as described.

2. A chimney-cap plate having along its upper edge afiue-flange, a, and diagonal to such flange lapping end edges, one of the end edges, to, being in the form of a flange angular to the body of the plate, substantially as described.

3. The combination, with a rectangular chimney-cap, of corner-clamps B, provided with a fluke, 13", and clamped to the cap-corners, substantially as described.

In testimony whereof I have hereunto set my hand this 18th day of August, 1888.

ADAM E. CLUTE.
